Trailhead Location and Access Points

Access to the trail typically begins with a long shuttle ride up a dirt road to reach the starting point high in the mountains above Oakridge. The route offers multiple access points, allowing riders to customize their experience based on skill level and time constraints.

For those seeking a shorter ride, an alternative starting point is available at the Upper Alpine trailhead, which provides access to a highly-rated 24-mile intermediate route. It’s important to note that this trail is designated for mountain bikes only, ensuring a dedicated experience for cyclists.

Elevation Profile and Key Climbs

The ATCA Trail presents a challenging elevation profile with significant climbs and descents throughout its 24.1-mile length. The route boasts an impressive total elevation gain of approximately 3,842 feet (1,171 meters), offering riders a true test of endurance and skill. The trail begins with a mellow climb from the trailhead, but riders should be prepared for more demanding ascents later in the journey.

One of the most notable climbs occurs after the Cloverpatch section, where cyclists face a grueling 1,500-foot ascent up Tire Creek Road and the Cloverpatch Tie Trail to rejoin the Alpine Trail. This climb is particularly challenging and requires careful energy management. For those seeking an even more intense experience, skipping the shuttle and pedaling to the trailhead adds approximately 5,000 feet of climbing to the route, resulting in a total elevation gain of around 9,000 feet. The ATCA Trail’s varied elevation profile contributes to its reputation as an epic backcountry ride, rewarding cyclists with exhilarating descents after conquering the demanding climbs.

Trail Difficulty and Skill Level Recommendations

The ATCA Trail is classified as a difficult mountain biking route, best suited for upper intermediate to advanced riders. The trail features mostly stable tread with some variability, including larger and more unavoidable obstacles such as bigger stones, roots, steps, and narrow curves. The technical difficulty is more advanced compared to lower intermediate trails, with steeper grades on slopes.

Riders should be prepared for a challenging backcountry experience that includes long descents, punchy climbs, and technical sections. The route demands strong bike handling skills, especially during high-speed descents through dense forest. Endurance is crucial, as the trail covers 24.1 miles with significant elevation changes. Given its remote nature and length, riders should also be self-sufficient and prepared for potential mechanical issues or changing weather conditions. The ATCA Trail is not recommended for beginners due to its technical features and the physical demands of the ride.
